What are you referring to as being positive? .i.e. nonfarm payroll growth is not good at this point.
The most predictive indicator is the unemployment ratio, and it's very low right now.
Perhaps inflation is a better predictive indicator, but we really don't know since we haven't had any for ~40 years. As I said, it's the uncertainty depressing markets IMO, not necessarily the outlook.
That's a lot of people not working that simply aren't in the market anymore, unemployment would look a lot worse if they were included.
